Octave Bandwidth High Power Non-Reflective Shunt PIN Diode Switch

Abstract:

A low-reflectivity solid-state switch circuit includes an input port configured to transmit an electronic signal and first and second output ports configured to receive the electronic signal. The switch circuit further includes a first switching element connected between the input port and the first output port, a second switching element connected between the input port and the second output port, a third switching element connected to a first conductive path between the first switching element and the first output port, and a fourth switching element connected to a second conductive path between the second switching element and the second output port. The third and fourth switching elements are utilizable to shunt current reflections from their connected conducted paths when the respective conductive path is configured in an off configuration.
